  • ASTAXANTHIN PRODUCTION USING A RECOMBINANT MICROBIAL HOST CELL
    Publication number: 20150167041
    Abstract: A recombinant microbial host cell is provided capable of producing astaxanthin from ?-carotene without a measurable concomitant accumulation of ketolated or hydroxylated intermediates such as adonixanthin, zeaxanthin, adonirubin, echinenone, 3-hydroxyechinenone, 3?-hydroxyechinenone, canthaxanthin, and ?-cryptoxanthin. Specifically, a ?-carotene producing microbial host cell was engineered to express two heterologous genes, a ?-carotene ketolase from Chlamydomonas reinhardtii in combination with a carotenoid hydroxylase from Brevundimonas vesicularis or Arabidopsis thaliana.
